Impermeable air-transport cover for fountain pens



Nov. 8, 1955 c. BARNARD IMPERMEABLE AIR-TRANSPORT COVER FOR FOUNTAIN PENS Filed Feb. 29, 1952 IN1/wrok dARLoS BAFA/ARD United States Patent O IMPERMEABLE Am-TRANSPORT COVER FOR FOUNTAliN PENS Carlos Barnard, Acapulco, Guerrero, Mexico Application February 29, 1952, Serial No. 274,032 1 Claim. (Cl. 1Z0-108) The present invention relates in general to covers, receptacles or sheaths, especially for fountain pens, and refers more particularly to a novel, useful, practical, and impermeable air-transport cover for fountain pens, specially designed to hold the fountain pen of a plane passenger and to prevent staining of the passengers clothes by leakage of ink from the pen, due to the atmospheric pressure resultant from the height, as happens very frequently.

It is a well-known fact that a plane passenger must empty his fountain pen before undertaking a flight, since otherwise the atmospheric pressure caused by the height at which the plane liies, extracts the ink, causing the passengers clothes to become stained and often mining them, Whether said passenger carries the pen on his person or put away in his luggage. It also occurs frequently that if the pen is kept in a brief-case, the papers or documents contained therein become badly spotted. To avoid such inconveniences, the air-transport cover for fountain pens, which is the object of this invention and which can easily be kept in ones pocket, with the pen inserted therein, has been designed.

From the foregoing, the principal object of the invention is to provide an impermeable cover or sheath, made in such a manner as to permit the insertion of the fountain pen, so that the latter may be carried with absolute safety and tranquility on a plane ight, inasmuch as said cover is lined with absorbent material so that if the ink comes out there will be absolutely no danger of staining ones clothes.

These and other details, advantages and features of the sheath or cover for fountain pens, of the invention, will be made clearly apparent in the following description as also in the drawings attached thereto in illustration thereof, the same reference numbers being used in said drawings to indicate the same parts in the three gures shown.

In said drawings:

Fig. 1 is an elevational view of an impermeable cover or sheath, constructed according to the invention, said gure showing its practical utility inasmuch as it illustrates a fountain pen properly inserted.

Fig. 2 is a vertical sectional elevational view taken on the plane indicated by line 2 2 of Fig. 1; and

Fig. 3 is a development of said cover or of the pattern used to form it, illustrating the absorbent material constituting the inner lining and also that of the outer covering.

Before describing in detail the impermeable cover for fountain pens, which is the object of the present invention, I wish it to be clearly understood that the drawings illustrate by way of example and in no manner by way of limitation, particularly insofar as concerns Fig. 3, one of the many ways of carrying out the invention, without limiting the latter to the specific details illustrated and described. Recourse may be had therefore to variations and modifications, particularly with regard to the pattern for cutting and making the cover, without departing from the principles of the invention and provided they come within the scope of the annexed claim.

2,722,916 Patented Nov. 8, 1955 ICC As illustrated in the attached drawings, the device of the invention is constituted by an elongated bag or receptacle such as that shown in Fig. l, such bag comprising an outer cover 10, made generally of cardboard, bristol-board, oilcloth, or any other material deemed convenient, having a lining 11 of absorbent material such as blotting paper. Said absorbent lining 11 wholly covers the interior of the cover 10 and projects from its upper edge 12, being turned down to form the culi 13, which overlaps the upper portion of said bag 10, as is clearly appreciated in Figs. 1 and 2 of the drawings.

This bag or cover is closed carefully on three of its sides, namely its lower or bottom edge 14 and its two sides 15 and 16, and is open at the top (edge 12), to permit of introducing into the inside thereof the fountain pen 17, the clip of which, 18, is secured to the turned-over cuff 13, in the manner clearly illustrated in Fig. l of the drawings.

The hermetic closure of the bottom 14 of the bag or cover and of its sides 15 and 16 may be elfected with any suitable means, for example by means of gummed strips or any adhesive, or also by means of the flanges (Fig. 3 of the drawings), intended to be adhered to the corresponding edges of the cut pattern of the device.

In said Fig. 3 of the drawings, the pattern for cutting the device is illustrated as having the fold 21, which forms one of its sides or edges 15-1'6, although it may likewise be made of two pieces joined at the sides and bottom, or with the fold forming the bottom 14 and uniting the two sides.

The turned-over cuff 13 at the upper end of the bag or cover serves the useful and practical purpose of drying and cleaning the pen immediately if upon withdrawing it, it should have any ink on the outside.

The absorbent lining 11 will pick up all the ink discharged from the pen, without its passing through to the exterior of the device, which is prevented by the external non-absorbent cover 10, whereby there is no danger whatsoever of the clothes of the person using the device of the invention becoming stained.

Having thus described the invention, what I consider as new and desire to secure by Letters Patent is:

An impermeable air-transport cover for fountain pens, comprising a narrow elongated envelope which is composed of an impervious outer cover sheet of non-absorbent material and an inner sheet of absorbent material completely lining said outer cover, said elongated envelope being hermetically sealed along its two longer sides and across its bottom, the top of said envelope being open to permit insertion of a fountain pen so that the pen is completely surrounded by the lining of absorbent material, said inner lining of absorbent material projecting beyond the upper edges of said outer cover and being folded over said outer cover to form a cuff on which the fountain pen clip may be secured and to provide a cleaning portion for use upon removal of the fountain pen.
